Pour tomato sauce in crock-pot. Add pork chops. Thinly slice onions on a mandolin slicer if available and add on top of chops. Add brown sugar, Worcestershire sauce, vinegar, hot sauce, salt and garlic.
Set slow cooker or crock-pot on low and let cook for 5-6 hours.
If you are there while cooking, spoon a little of the sauce over chops every couple of hours. If not don't worry they will come out terrific. Serve over white rice. Enjoy!
